Firefighters had to rush into the blaze when they first got to the scene, as they searched through the flames, but thankfully, no one was inside.

We will always call that kind of act brave, but they will always respond because it's just part of the job.

"Um, you know, this is what we do," said Capt. Aaron Ernsberger, of Phoenix fire. "I mean, this is why the Phoenix Fire Department firefighters are so proud to be here. They love their job and so, we're happy to do it."

There's not much left of the vacant house; the roof is practically gone, the streets are filled with foam from the fire fight and investigators are still sifting through the damage, as they try to figure out what happened.
